摘要
提出了“能量价值分析”理论 ,并推导出了“综合成本煤耗率”的计算公式。此方法克服了传统热力学分析方法的局限 ,把热力学和经济学有机地结合在一起。以单位能量价值为基础 ,分析发电厂在能量转换过程中的能价增值及其利润 ,涉及到发电煤耗、厂用电率、电价和标煤原价等。能量价值分析结果表明 ,电的能价比燃料的能价高得多 ,因此节电比节煤效益更好。
Energy-saving measures for further improving the energy-saving work in power plants after separation of Plants and Grids are presented, the principle of 'Energy price analysis' being emphasized, and the formula of calculating 'coal consumption rate in integrated cost' deduced. This method eliminates limitations of traditional thermodynamic analysis method, to combine the thermodynamics organically with the economics together. Taking the unit energy value as the basis, the added value and the profit of energy price during the time of energy transformation in power plants are analysed, including coal consumption of power generation, auxiliary power consumption rate, electrical energy price, and original price of standard coal etc.. The results of energy price analysis show, the price of produced energy is much higher than the price of fuel, therefore, the effectiveness of electricity-saving is much better than coal-saving.
